Before I started maintaining the AVR backend, this instruction never originally used to have an earlyclobber flag. Some time afterwards (years ago), I must've added it back in, not realising that it was left out for a reason. This pseudo instrction exists solely to work around a long standing bug in the register allocator. Before this commit, the LDDWRdYQ pseudo was not actually working around any bug. With the earlyclobber flag removed again, the LDDWRdYQ pseudo now correctly works around PR13375 again. llvm-svn: 326774 |
